N2 - Many liquefaction countermeasures have been developed by researchers all over the world. The drainage approach is considered to be one of the most successful among those. However, most research focused on utilizing this method for newly constructed structures. In this research, a sustainable and low-cost technique for existing infrastructures is proposed. Gravel-tire chips mixture (GTCM) as an alternative drainage enhancing geomaterial has been adopted here. A series of model tests were conducted using shaking table. The results indicated that excess pore water pressure beneath the building quickly dissipated through GTCM drains during the shaking. The drainage system successfully prevented the liquefaction leading to the significant reduction of the settlement of the structure.
